PITTSBURGH – Pascal Dupuis scored twice, Marc-Andre Fleury made 26 saves, and the top-seeded Pittsburgh Penguins opened the playoffs with a 5-0 romp over the New York Islanders on Wednesday night.

Beau Bennett, Kris Letang and Tanner Glass also scored for the Penguins, who had no trouble against the upstart Islanders even with star Sidney Crosby sidelined by a broken jaw. Pittsburgh hardly needed its captain to continue its mastery of the Islanders, who made their first playoff appearance since 2007.

The Penguins, the No. 1 seed in the Eastern Conference, beat Evgeni Nabokov four times in the game's first 22 minutes, including goals by Letang and Dupuis 32 seconds apart early in the second period to send Nabokov to the bench after he stopped just 11 shots.
